The Sun Proves Carbon-14 Dating Inaccurate?

Once again, when it comes to science, something we thought was a constant…

Isn’t.

All thanks to the sun.

I must say, I love it when known ‘facts’ are disproved – It always opens the door for so many new and interesting discoveries!

Bring them on!

And, just because I care, I have read this whole article numerous times and bolded what I deem the important parts. You can just read those and save time, although I think this WHOLE article is definitely ready-worthy:

[Source:io9.com] The Sun is changing the supposedly constant rates of decay of radioactive elements, and we have absolutely no idea why. But an entirely unknown particle could be behind it. Plus, this discovery could help us predict deadly solar flares.

It’s one of the most basic concepts in all of chemistry: Radioactive elements decay at a constant rate. If that weren’t the case, carbon-14 dating wouldn’t tell us anything reliable about the age of archaeological materials, and every chemotherapy treatment would be a gamble. It’s such a fundamental assumption that scientists don’t even bother testing it anymore. That’s why researchers had to stumble upon this discovery in the most unlikely of ways.

A team at Purdue University needed togenerate a string of random numbers, a surprisingly tricky task that is complicated by the fact that whatever method you use to generate the numbers will have some influence on them. Physics professor Ephraim Fischbach decided to use the decay of radioactive isotopes as a source of randomness. Although the overall decay is a known constant, the individual atoms would decay in unpredictable ways, providing a random pattern.

That’s when they discovered something strange. The data produced gave random numbers for the individual atoms, yes, but the overall decay wasn’t constant, flying in the face of the accepted rules of chemistry. Intrigued, they checked out long range observations of silicon-32 and radium-226 decay, both of which showed a slight but definite variation over time. Intriguingly, the decay seemed to vary with the seasons, with the rate a little faster in the winter and a little slower in the summer.

At first, the researchers tried to rationalize the seasonal fluctuations as the result of instrument error, perhaps caused by changing heat and humidity. But that idea fell apart when nuclear engineer Jere Jenkins noticed the decay rate of the short-lived isotope manganese-54 dropped slightly during a solar flare. In fact, the decrease began a good 36 hours before the flare occurred.

That suggests two things: one that’s theoretically puzzling, and another that’s hugely exciting from a practical perspective. If decay rates really are affected by solar flares before the flares even occur, that could provide the first truly reliable early warning system for flares. Considering severe solar flares can wreak havoc on electrical grids and even kill astronauts who aren’t properly protected, that would be a huge benefit for humanity.

But practical pluses aside, why is this happening? The seasonal fluctuations suggested the Sun could be involved somehow, and the solar flare connection confirmed it. The scientists speculated that solar neutrinos, the nearly massless particles created as byproducts of the sun’s fusing of hydrogen atoms into helium, might be causing these variations. The fact that these neutrinos pass straight through the Earth with ease fit well with the fact that the decay rates were changing even at night, when the entire planet was between the radioactive isotopes and the Sun.

Once the researchers conclusively ruled out environmental influences, that left the Sun as the only possible cause of the decay variations. They also found that the amount of change varied in time with the Earth’s orbit – the effect was greater when the orbit brought the Earth closer to the Sun and thus into contact with more neutrinos.

That’s where renowned Stanford physics professor Peter Sturrock entered the picture. Confronted with this mystery, he advised the researchers to test how the decay fluctuations correlated with the Sun’s own rotation. They found the decay rates recurred every 33 days, which didn’t quite fit with the Sun’s known surface rotation length of 28 days. But the neutrinos wouldn’t be coming from the surface – they would be coming from deep inside the core. Unlikely as it might seem, the sun’s core must be rotating a little slower than its surface, apparently once every 33 days.

All of this relies on some unlikely assumptions and the occasional bold intuitive leap, but the model they propose seems to hang together. And yet one mystery remains – how are the neutrinos managing to interact with the radioactive particles in this way? It doesn’t fit with the known behavior of neutrinos, and it opens up the very real possibility that some previously unknown subatomic particle is actually behind this bizarre effect.

As Peter Sturrock explains:

“It’s an effect that no one yet understands. Theorists are starting to say, ‘What’s going on?’ But that’s what the evidence points to. It’s a challenge for the physicists and a challenge for the solar people too. [If it’s not neutrinos,] it would have to be something we don’t know about, an unknown particle that is also emitted by the sun and has this effect, and that would be even more remarkable.”

If these new discoveries hold up, then we’ve discovered that the sun changes rates radioactive decay, that we can predict solar flares before they happen, that the sun’s core rotates slower than its surface, and maybe even that an entirely unknown particle exists and is affecting our world in a tangible way. Not a bad set of results for what was supposed to be a simple search for some random numbers.

While you were sleeping…

fra Giovanni 1513 AD

There is nothing I can give you
which you have not;
but there is much, very much, that,
while I cannot give it, you can take.

No heaven can come to us unless our hearts
find rest in today. Take heaven!
No peace lies in the future which is not hidden in
this present instant. Take peace!

The gloom of the world is but a shadow.
Behind it, yet within our reach is joy.
There is radiance and glory in the darkness, could we but see,
and to see, we have only to look. I beseech you to look!

Life is so generous a giver, but we, judging its gifts by
their covering, cast them away as ugly, or heavy or hard.
Remove the covering and you will find beneath it
a living splendor, woven of love, by wisdom, with power.

Welcome it, grasp it, touch the angel's hand
that brings it to you. Everything we call a trial, a sorrow,
or a duty, believe me, that angel's hand is there, the gift is there,
and the wonder of an overshadowing presence.
Our joys, too; be not content with them as joys.
They, too, conceal diviner gifts.

Life is so full of meaning and purpose, so full of beauty,
beneath its covering, that you will find
earth but cloaks your heaven.

Courage, then, to claim it, that is all. But courage you have,
and the knowledge that we are all pilgrims together,
wending through unknown country, home.

And so, at this time, I greet you.
Not quite as the world sends greetings, but with profound esteem
and with the prayer that for you, now and forever,
the day breaks, and the shadows flee away.

Literary Anguished Excerpt

"My friend.--Welcome to the Carpathians. I am anxiously expecting you. Sleep well tonight. At three tomorrow the diligence will start for Bukovina; a place on it is kept for you. At the Borgo Pass my carriage will await you and will bring you to me. I trust that your journey from London has been a happy one, and that you will enjoy your stay in my beautiful land.--Your friend, Dracula."

4 May--I found that my landlord had got a letter from the Count, directing him to secure the best place on the coach for me; but on making inquiries as to details he seemed somewhat reticent, and pretended that he could not understand my German.

This could not be true, because up to then he had understood it perfectly; at least, he answered my questions exactly as if he did.

He and his wife, the old lady who had received me, looked at each other in a frightened sort of way. He mumbled out that the money had been sent in a letter, and that was all he knew. When I asked him if he knew Count Dracula, and could tell me anything of his castle, both he and his wife crossed themselves, and, saying that they knew nothing at all, simply refused to speak further. It was so near the time of starting that I had no time to ask anyone else, for it was all very mysterious and not by any means comforting.

Just before I was leaving, the old lady came up to my room and said in a hysterical way: "Must you go? Oh! Young Herr, must you go?" She was in such an excited state that she seemed to have lost her grip of what German she knew, and mixed it all up with some other language which I did not know at all. I was just able to follow her by asking many questions. When I told her that I must go at once, and that I was engaged on important business, she asked again:

"Do you know what day it is?" I answered that it was the fourth of May. She shook her head as she said again:

"Oh, yes! I know that! I know that, but do you know what day it is?"

On my saying that I did not understand, she went on:

"It is the eve of St. George's Day. Do you not know that to-night, when the clock strikes midnight, all the evil things in the world will have full sway? Do you know where you are going, and what you are going to?" She was in such evident distress that I tried to comfort her, but without effect. Finally, she went down on her knees and implored me not to go; at least to wait a day or two before starting.

It was all very ridiculous but I did not feel comfortable. However, there was business to be done, and I could allow nothing to interfere with it.

I tried to raise her up, and said, as gravely as I could, that I thanked her, but my duty was imperative, and that I must go.

She then rose and dried her eyes, and taking a crucifix from her neck offered it to me.

I did not know what to do, for, as an English Churchman, I have been taught to regard such things as in some measure idolatrous, and yet it seemed so ungracious to refuse an old lady meaning so well and in such a state of mind.

She saw, I suppose, the doubt in my face, for she put the rosary round my neck and said, "For your mother's sake," and went out of the room.

I am writing up this part of the diary whilst I am waiting for the coach, which is, of course, late; and the crucifix is still round my neck.

Whether it is the old lady's fear, or the many ghostly traditions of this place, or the crucifix itself, I do not know, but I am not feeling nearly as easy in my mind as usual.
